What happens when one thing you despise collides with something you love? I happened upon the 3am rebroadcast of the Tonight Show, which I loathe, while the greatest band in the world: Alison Krauss + Union Station was performing. It caused some cognitive dissonance for me to see this musical institution I adore on a show I hate. Apparently, they did two performances on Wednesday and Thursday of last week. Now, usually the musical acts on the Tonight Show are pop de rigueur aren't they? I think the show is playing mind games with me.
